| carrys nerve impulses from receptors or sense organs toward the central nervous system | |
| activated by, characteristic of, or secreting epinephrine or related substances, particularly the sympathetic nerve fibers that liberate norepinephrine at a synapse when a nerve im | |
| minimal stimulus that produces excitation of any structure, eliciting a motor response | |
| thicker muscle filament -- has cross-bridges | |
| thinner muscle filament made up of ___ , troponin, and tropomyosin -- slides past thicker | |
| Relays AP to SR to release Ca2+ | |
| the distance between two Z lines -- shortens during contraction | |
| A local change in the depolarization produced in the postsynaptic neuronal membrane in response to an excitatory impulse; summation of these depolarizations can lead to discharge o | |
| the neural pathway that mediates a reflex action/motor response | |
| change in membrane potential occurring in nerve, muscle, or other excitable tissue when excitation occurs | |
| The wavelike muscular contractions of the intestine or other tubular structure that propel the contents onward by alternate contraction and relaxation | |
| a muscle that flexes a joint | |
| the center of a sarcomere -- narrows during contraction | |
| a group of nerve cell bodies, located outside the central nervous system | |
| contraction where muscle tension changes, but length stays the same | |
| band of myosin in a muscle | |
| functions of internal organs | |
| part of muscle in which myosin is absent, contains Z line -- narrows during contraction | |
| a drug that has an affinity for and stimulates physiologic activity at cell receptors normally stimulated by naturally occurring substances | |
| a substance that tends to nullify the action of another, as a drug that binds to a cell receptor without eliciting a biological response, blocking binding of substances that could | |
